Death Wave — Stephen Coonts; William H. Keith

In Central Asia, a dangerous shipment has vanished. Twelve nuclear warheads -- with a combined power greater than the Hiroshima bomb -- have been stolen by a deadly new alliance of international terrorists. Their plan: Use man-made weapons to trigger a devastating natural catastrophe -- the largest tsunami the world has ever seen…

Enter Deep Black: a secret unit of the NSA led by former Marine sniper Charlie Dean. With his hand-picked team of special ops, Dean follows the terrorists' trail to the Canary Islands. But time is running out. In hours, the warheads will be detonated and a thousand-foot wave will rise. In it's path of destruction lies every city on America's eastern coast.
